Title: Separate Bishop and Knight Outpost Bonuses

Basically what it says...
Modified the formula to make it more transparent.
No functional changes.

Bishops probably don't need/benefit as much knights from outposts, so it may make sense to allow the extra bonuses for friendly pawn support and no minor enemy pieces able to attack to scale independently.
